How to upload a cue sheet?

Once you've done that you're ready to go. The upload
procedure is simple - first you need to log in to CueDB, then
you have 3 minutes to start uploading the file from the client
application.

Any CueDB client application has to compute a
TTH root for the reference file (*.mp3, *.bin, etc.) and
send it to CueDB along with the cue sheet and other required
information (name, size, bitrate, length, etc.).
